A custom version of the blackMagic probe with rust in it

Pick the pre-built firmware for your board or build from source.

'see wiki for exact pinout' ### 3. Start debugging

Or use any GDB frontend (VS Code, CLion, etc.) — just point it to the serial port.

This project uses CMake with presets for each target platform.

There is a devpod/docker build environment included.

- CMake ≥ 3.21 - ARM GCC toolchain (arm-none-eabi-gcc) or LLVM/Clang - RISC-V toolchain (for CH32V targets) - Rust toolchain (for the GDB interface)

Gd32f303 revG: common questions

What microcontroller does the Gd32f303 revG use?

The Gd32f303 revG is built around the GD32F303, from the STM32 family.

How big is the Gd32f303 revG PCB?

The Gd32f303 revG measures 49.2 × 31.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Gd32f303 revG?

42 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gd32f303 revG design files?

From the mean00/swindle repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Gd32f303 revG design in my own project?

The repository has no license, so all rights stay with mean00. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Gd32f303 revG without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
